Can a honda dio run 250 kms in one day?

I'm planning for a one day journey, pune-mumbai-pune
Can my 6 months old dio run such distance?
It will be around 250 kms?
Please leave some suggestions

10 mins gap every 50 km

Yes, you can safely ride your Honda Dio from Pune to Mumbai and back in one day, but make sure you do the following:

1. Maintain speed at around 65 - 70 kmph. If you ride any faster, you will put undue stress on the engine, which could lead to overheating.

2. Start with a full tank of fuel. Fill up your fuel tank to the brim before you start, and top it up again once you reach Mumbai. Scooters tend to deliver low mileage when cruising at highway speeds, and this way you can ensure you don't run out of fuel in the middle of nowhere.

3. Carry a tubeless tyre repair kit. One of the Dio's plus points is that it comes with tubeless tyres as standard. In case of a puncture, tubeless tyres can be repaired very easily. Having a repair kit will come in handy. (Learn how to repair tubeless tyre punctures here: http://www.choosemybike.in/latest-bike-news/how-to-fix-a-tubeless-tyre-puncture)
